IMPROVEMENT m REVOLVING ULTlVATORS-.

Specification forming part of Letters Patent No. 15S663, dated January 12, 1875 application filed uly 16, 1874. I

To all whom it may concern Be it known that L'NATHANIEL S. Woon,

in the county of Boone and State of Missouri, have invented a new and useful Improvement in Rotary Cultivators; and. I do hereby deelare the following to be a full, clear, and are act description thereof, reference being had to theaccompanying drawing, forming a part of this specification.

v The invention relates to corn and cotton cultivators, and will .be first fully described, and then pointed out in the claims.

Figure l is a longitudinal sectional eleva tion, and Fig. 2 a plan m'achine. v Similar letters of reference indicate corresponding parts.

'2 2.represent slightly-flexiblearched iron vbars, uniting two'wo'odeu rectangular frames, 1 1, supported by the traction-wheels3 3, firmly fixed upon separate axles b b. 8 8 are View, of the improved shafts, revolving in journal-boxes secured to the rear, transverse, and inner longitudinal bars of frames 1 1, and provided with the beveled gear-wheels'et 4, gearing with the beveled gear-wheels 4 4, firmly fixed on axles b b, thus giving a rotary motion to the shafts 9 9, universally jointed to shafts 8 S at 15 15, and projecting rearward, carrying the plow-hoes a in their revolutions. The inner ends or shanks of the hoes a are square, and are inserted on. a spiral line in shafts 9 9, and firmly fastened therein by means of a screw and tap on the p H end of each, and may be changed at pleasure,-

so as to penetrate the earth at various angles.

1 13 is a pivoted lever or'han'dle, projecting rearward from the top of the rear arched bar 2, to

which are attached the pendent rods 11 11,- holding and supportingin their looped ends the rear ends of shafts 9 '9. 12 is a transverse bar, uniting and regulatingthe angular direction of the pendent rods l1 11. 14.1.; are sections of the tongue.

It will be observed that, by means of the wheels 3 3 operating on separate axles b b, the difiiculty otherwise experienced in turning the machine is avoided. I

my invention I hereunto set my hand this 28th day of November, 18.70.
